Abstract:
A lighting device 12 includes a light source 17, a chassis 14 housing the light source 17 and an optical member 15a provided to face the light source 17. The optical member 15a includes a light source overlapping portion DN that overlaps a light source installation area of the chassis 14 where the light source 17 is arranged and an empty area overlapping portion DN that overlaps an empty area LN of the chassis 14 where no light source 17 is arranged. A light reflecting portion 40 is formed on at least the light source overlapping portion DA such that light reflectance of the light source overlapping portion DA is relatively higher than that of the empty area overlapping portion DN. A color adjustment portion 50 is formed on the optical member 15a to adjust color of the light source overlapping portion DA and the empty area overlapping portion DN.
